Clinical Impact of Rapid Prototyping 3D Models of Congenital Heart Disease on Surgical Management

Brief Summary

      Patient-specific, 3D printed models have been utilized in preoperative planning for many
      years. Among researchers and clinicians, there is a perception that preoperative exposure to
      3D printed models, derived from patient images (CT or MRI), aid in procedural planning. 3D
      printed models for heart surgery have the potential to improve a clinician's preparedness and
      therefore may reduce surgically-related morbidity and mortality. This randomized clinical
      trial aims to evaluate whether pre-procedural planning of surgeons exposed to a
      patient-specific 3D printed heart model will decrease cardiopulmonary bypass time, morbidity,
      and mortality.

Detailed Description

      3D imaging and rapid prototyping 3D printing technology have advanced to the point where it
      is feasible to marry the two to produce a patient-matched and accurate 3D model of congenital
      heart defects. The production of a 3D model of the heart may be particularly useful in
      anticipation of surgery such that the operator can plan and visualize the surgery prior to
      the surgical date with a physical heart he or she can manipulate in their hands.

      Preliminary studies demonstrate potential for clinical impact of 3D models on patient care
      and patient outcomes. 3D models have long been shown to enhance education and communication
      of anatomy. In 2008 Kim et al reviewed 3D printed models as an emerging technology in
      management of congenital heart disease, and also suggests that physical models may also help
      enhance patients and physicians' understanding of congenital heart disease. Our group has
      also published on the clinical and educational value of these 3D heart models. To date, no
      systematic trial identifying the value of 3D models on procedural planning has been

             a. Images will be validated by the IRC prior to inclusion

          -  Written informed consent (and assent when applicable) and HIPAA authorization obtained
             from subject or subject's legal representative and ability for subject to comply with
             the requirements of the study.

        Exclusion Criteria:

          -  Complex defects involving atrioventricular valve anomalies

               1. complete or transitional atrioventricular canal

          -  Defects with valve dysfunction requiring an extensive valvuloplasty

          -  Patients with a contraindication to MRI scanning will be excluded unless they are
             referred for a cardiac CT per clinical standard of practice. These contraindications
             include patients with the following devices:

               1. Central nervous system aneurysm clips

               2. Implanted neural stimulator

               3. Implanted cardiac pacemaker or defibrillator which are not MR safe or MR
                  conditional according to the manufacturer

               4. Cochlear implant

             scheduled surgical date

          -  Subjects where date of scan to date of surgery is less than 10 calendar days

          -  Subjects where MRI or CT reconstruction is limited due to poor image acquisition as
             solely determined by the Image Reconstruction Center.
